Specification of Letters Patent. Patented Aug. 22, 1922.,

Application filed September 29, 1919. Serial 150.327,?272.

To all whom it may concern:

Be it known that I, RUSSELL DWIGHT, a citizen of the United States, anda resident of- Wyoming, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in the Process ofForming Imitation Leather Upholstery and the Product Produced Thereby,of which the followin is a full, clear, and exact description, re erencebeing had to the accompanying drawing, forming part of thisspecification.

In the use of artificial leather for upholstering particularly in theupholstering of the seats in carriages, automobiles and the like, it isnecessary to pack or stuff the back of the artificial leather with softmaterial such ias cotton batting before the leather is applied to thecushions and in order to secure the pockets for holding the packingmaterial to the artificial leather, it has been found necessary to plaitthe leather in order to .conceal the stitches and to prevent the wearand breaking of the stitches in use.

Where artificial leather is used for upholstering in the seats ofautomobiles these plaits necessarily gather dust, and the requirement ofplaiting necessitates the employment of very much more material thanwould be needed should the plaits be omitted, and obviously thepreparation of the goods is slow and laborious, and each plait has to bemade, folded and sewed by itself.

It is to obviate these difficulties that my invention is directed, andit consists essen tially in the process whereby the pockets for thepadding are formed and secured to the backing to which theartificial'leather composition is applied before the manufacture of theartificial leather.

In the drawing which accompanies this application,

Figure Iis a section of one construction of the material illustrating myimproved process.

Figure 2 is a section of another construction of material.

There are a number ofmethods for the manufacture of artificial leather,but the general plan pursued is to apply a coating of the required pasteusually to any kind of cotton cloth desired. Such pastes are procurableon the market, formed of a cellulose base, and sometimes calledleatherizing dope.

In carrying out my process, before the cloth is treated with theartificial leather composition, I form pockets by sewing folds ofsuitable cloth on one side of the backing which is later to be coatedwith the artificial leather composition.

1 lndicates a section of this backing, and 2 the-cloth secured theretoby stitches 3 directly through the material so as to form the pockets 4.In Figure 1, as shown, the amount of material in the loops 2 maynaturally vary dependent upon the desired result, even to the extent .ofbeing fiat with and prior to the stufling thereof, the top piece ofcloth which is still flat is subjected to the artificial leather coatingand other processes to make up the desired kind of artificial leather inthe usual manner. When the artificial leatherprocesses are completed andthe required leather surface has been given to the cloth, the materialis ready for the packing, and the pockets are filled or stuffed with thecotton bats or other desired filling to form the finished article. Theresult of stuifing the form shown in FigureQ will be to form either aflat surface for the backing 1, or if more tightly stuffed with ridgescorresponding to the pockets. The form shown in Figure 3 will fgormallypresent only a fiat leatherized surace.

By thus securing the pockets for the cotton bats to the backing to whichthe artificial leather composition is to be applied before treatment, agreat saving of time and labor results. The pockets can be seweddirectly to the backing on a gang machine, and there is no need toconceal the stitches by plaits. The artificial composition efiectivelyconceals the stitches and prevents wear and decay while the avoidance ofplaits enlarge saving in material. The cushions are smooth and there areno folded portions to collect dust, and the goodsare not subject to thewear at the edges of the folds incident to the old methods.

While I have illustrated two constructions of pockets, it will, ofcourse, be understood that other Ways will readily suggest themselves.The essential feature of my invention consists as already indicated informing the pockets or holders for the cushions on the artificialleather backing before the leather coating is applied, and not in theparticular construction of the pockets or the manner of their attachmentto the material. Also another point in my invention is the treating ofthe backing with the leatherizing dope, prior to stuffing the pockets.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:-

1. The process of manufacturing artificial leather upholstery whichconsists in stitching together two pieces of cloth or other suitablematerial with rows of stitches, then applying artificial leathercomposition to one of the exposed surfaces and then filling the openingsbetween the rows of stitches with suitable padding material.

2. The process of manufacturing artificial leather upholstery whichconsists in stitching together two pieces of cloth or other suitablematerial with parallel rows of stitches, then applying artificialleather composition to one of the exposed surfaces and then filling theopenings between the rows of stitches with suitable padding material.

3. The process of manufacturing artificial leather upholsterywvhichconsists in -stitching together two pieces of cloth with parallel rowsof stitches, one piece forming pockets or loops With reference to theother, then applying artificial leather composition to the exposed flatfabric and then filling the pockets with suitable padding material.
